Confused Ubuntu-ist installing JDK7

It started when I decided to try to make $100 for a program that would run full screen. I knew I should use Java because the guy who wants the app runs Windoze 7. I installed eclipse and found a website that had an example of running Java full screen:

They came to the conclusion that I needed to get rid of GNU stuff (something that I am not sure how to do) and told me to install a new JDK. Someone on the forum tested my code on Windoze and said it ran fine. I hemmed and hawed at all the manuals to read and all the choices and they held my hand through it but I guess they are sick of it now. I ended up going to this site:

Re: Confused Ubuntu-ist installing JDK7

It looks to me as though you're installing 64-bit Java on a linux-pae system. I'm not convinced it *won't* work, but I have severe doubts that it will work properly. If I was using PAE, I think I'd install the 32-bit JVM. The reason is that even though PAE gives you access to more than 4GB RAM, your applications (I might have this bit wrong) can only access 4GB at once - as though they're stuck in a 32-bit bubble. If I was you, I'd either go 64-bit everything, or 32-bit everything. If you have more than 2GB in your PC, perhaps PAE + 32-bit Java is the right combination.
